4 IMPROVEMENT IN WIRE HEDDLES FOR LOOM-HARNESS'.

Specification forming part of Letters Patent No; 49,251 dated August 8 1865.

ing had to the accompanying drawings, and to the letters of reference marked thereon, in

` Figure 1 is a front view of a heddle made according to my invention, and Fig. 2 is a side view.

This invention consists in making a heddle so that its body shall be composed of only one strand ofwire or other material of which'it may be made, thereby securin g lightness with suicient strength; and it also consists in so forming the eye that it shall have a smooth lsurface without angles in its ends, asin the wire and loops, so that their sides consist of separate strands which are brought together at the ends of the eyes and loopsand then twisted one upon another, while those portions which lie between the eyes and loops are of course double, consistingof both the strands of wire.'

The eyes terminate at each of their ends in sharp angles made by bringing` the-two strands together in the manner just described. These angles are very disadvuntageous and objectionable in weaving, because the yarn is apt to be caught in them when the harness is raisingvthe shed lin the operations of weavin g, `and the strands are often frayed and some-times broken in consequence thereof. The loops have like angular terminations; but since they serveonl y the purpose of securing the heddle in its frame, theirconst'ructionis not so objectionable in this respect. Y

My invention has for its object to Inake a heddle whose eye has a smooth inner surface without angles or crevices at its ends o'r elsewhere to fray or catch the yarn of the warp, and also to lessen its weight and cost by making the heddle'ot' a single strand.

y In the example of myinvention here shown the heddle A is made of a single strand of wire. The loops C C, which furnish the means of securin git in the heddle-frame, are made by bending the endsl of' theV wire so as to form oblong openings. The wire at the beginning of the loops is rst bent outward, as at c, to make anv offset from the strand equal to half the width ofthe loop. The loop is then completed by Vbending the end of the wire into the shape shown inthe drawings, its extremity being brought beneath the shoulder or offset e, and curved or bent so as with that offset to form a half-circle; or the loop may be formed-in the way shown at the upper end of theheddle in Fig. 2, the end of the wire being brought near to the offset e and the side ot the loop left partly open. The loops are so formed and ar-H ranged that if the axial line ofthe strand composing the body of the heddle be extended through the loops it will be coincident with their longer axes. This is accomplished by means of the oi'set e.

`The eye B is an oblong opening situated at about the middle of the length ofthe heddle,

made by reversing. the directions of theends 1 of the strand, and layingthe portions between the curved parts 'd d over or upon each other, as seen at a b, Fig. 2. At each end of the eye the strand is bent to a half-circle, the portions between bei-ng straight and parallel with each other. After the eye is formed each strand is bent inward, as at d, to bring` it into coincidence with the longer axis of theeye, the curves at d being also Acoincident with the ends ofthe eye.

nected to eachother by soldering or other `sui t able means at the points d d, and also, lif de-` sii-ed, between those points, for the purposeof prcventin g the parts composn g the eye'from springing apart by their own elasticity, or from without it. This mode of constructing heddles enables me to make a great saving in stock, bey The layers which compose the 'eye are con-` cause they are formed of only one strand iny stead of two, as heretofore. 1 thereby also decrease their weight, and consequently less power is needed to cause the necessary reci p rocations of the harness, and the wear of those parts of the lo'om which are connected with the harness is lessened. 'I also prevent the (lifticulty which forms a prominent objection to wire heddles as heretofore made--n amely, that of catching and raising the Warpby making their eyes smooth, so that'the yarn or warpthread cannot lodge or be caught or be frayed' in them.

.It will be observed that I preserve the rotundity of the strand in the formation of the eye, and also form it without angles or crevices. Any material capable of being bent in the way described, and which has a smooth surface and strength enough to retain the shape given to it,ma.y be used instead of wire, and strands of yen 'ylkind-of metal or metallic composition vmay be used.

'Having :thus described my invention, what I claim as new, and desire to secure by Letters
